Good painting is the kind that looks like sculpture.

A good artist ought never to allow impatience to overcome his sense of the main end of art - perfection

I live in sin, to kill myself I live; no longer my life my own, but sin's; my good is given to me by heaven, my evil by myself, by my free will, of which I am deprived.

The idea is there locked inside. All you have to do is remove the excess stone.

An artist does his most difficult work when he steps back from the blank canvas and thinks about what he is going to create.

Let it be enough for you to have bread and live virtuously and poorly like Christ, as I do here. I live meanly and don't bother about life or honor ... and I live with the greatest toil and a thousand worries. It is now about 15 years since I had a happy hour.

There is no greater harm than that of time wasted.
